Education and training
The WG Education and Training aims to increase interaction and knowledge dissemination between the different members of the EWRS. By providing training courses and workshops in different fields of weed science, the WG aims to cover a broad range of topics ranging from theoretical courses to practical trainings in the field. This offered activities focus on participants from weed science as well as crop science, plant science and ecology.
Crop Weed interactions
The EWRS Working Group "Crop-Weed Interactions" focuses on the interactions between crop and weed plants occurring after emergence of weedy plants in a crop stand. Attention is given to a fundamental understanding of processes governing crop-weed interactions as well as the utilization of this knowledge for improved weed management. Special attention is given to parasitic weed biology and ecology, and interactions between parasitic weeds and the crop.
We will facilitate the effective management of herbicide resistance by fostering understanding, co-operation and communication between industry, government, academic and farmers.
Invasive Alien Plants
Invasive Alien Plants are creating new problems worldwide as new weeds in managed and unmanaged areas as well as being among main causes of biodiversity loss. Alongside global change, new introduction of alien species are inevitable and will be bigger problem if required measures cannot be taken. In addition introductions and impacts have increased combined affect with other drivers such as climate change and disturbing habitats so on.
Physical and Cultural Weed Control
The objective of the WG is to promote international collaboration and support of research and information exchange on physical and cultural weed control. Physical and cultural weed control comprises cultural methods (e.g. crop rotation, soil tillage, mulches) and physical techniques (e.g.mechanical weed control, thermal weed control, electroweeding). Physical and cultural weed control methods are important aspects for the development of Integrated Weed Management systems with a reduced herbicide dependence. This WG addresses the development of single tactics and tools, and focusses on the combined use of these techniques in IWM approaches for sustainable agriculture in Europe. The WG organizes biannual meetings and excursions.
Precision Agriculture is based on the fact that weed populations are commonly irregularly distributed within crop fields and it implies applying chemical and/or physical weed control measures only where and when they are really needed.
Soil Seed Bank, Germination and Early Growth
The scope of the working group is: From weed seeds enter the soil to emerged seedlings (early growth) and from formation of vegetative reproductive organs to above ground shoots are formed.
Sustainable Use of Herbicides
The objective of the WG is to promote research and exchange of information on the optimum use of herbicides in Integrated Weed Management programmes. Special attention is paid to the role of herbicide-tolerant crop varieties in IWM strategies.
Weed Management in Mediterranean Cropping Systems
Recent climate change generated an agronomical shift towards more irrigated cropping systems in arid and semi-arid regions, leading towards shifts in weed species and biodiversity changes. As a working group, our mission is to share and promote collaborative research in order to create sustainable weed management in the arid and semi-arid countries of Europe under the projected climate change. We want to create new and improved weed management options suitable to the regional changes. The working group focuses on various cropping systems including arable and vegetable systems.
Weed Vegetation and Biodiversity
We are a group of weed scientists, agroecologists, botanists and specialists from others disciplines, who are interested in weeds from a conservation perspective, in the composition of the arable floral in response to management tools, in ecosystem services provided by weeds, and in the role of weeds in supporting food webs and the implications this has for the control of weed communities. Mapping of weed communities is an important tool to analyse weed community dynamics and design landscape wide weed management strategies.
